Terms and Conditions (Numbrs app)

Last updated: November 4, 2021

The Numbrs App is provided by and you are contracting with Numbrs Personal Finance AG, Neuhofstrasse 12, 6340 Baar, Switzerland (hereinafter referred to as “Numbrs”, “we”, “us”, “our”). The present terms and conditions (“Terms”) set out the agreement under which we may provide you with use of the Numbrs App and our services associated with the Numbrs App.

If you have any questions about these Terms, please contact our Support team at Numbrs provides its services exclusively on the basis of these Terms. Details regarding our authorised representative and further information can be found in the Contact Us section of our website.

  1. Scope

    These Terms apply to every user of Numbrs (hereinafter referred to as "you" or "User"). For more detailed information on how we handle your personal data we refer to our Data Privacy Notice ("Privacy Notice") which can be found by clicking on this link. No other terms or conditions apply to the provision of the Numbrs App and its associated services, the Numbrs Website, the Bitcoin Account and Numbrs Research described in section 3 (the "Services"), except as set out in the Terms, unless we have agreed otherwise with you in writing.
  2. Your agreement with Numbrs

    1. Creating a Numbrs User Account

      The use of the Numbrs App and the Services is not intended to be available to Users for persons under the age of 18 (or the relevant age limit applicable at their place of residence). If you are under the age, you are unfortunately not permitted to use the Numbrs App.

      In order to use the Services, you must (1) satisfy the age requirements, (2) be authorised to enter into a legally binding contract with us and not be prevented from doing so by applicable laws, and (3) be located in a country where our Services are available.

      Numbrs will provide you with the Services, as soon as you create a user account ("Numbrs Bitcoin Account") and start holding crypto assets assets in your Numbrs Bitcoin Account. To create a user account, you must provide us with all the data as required in the registration form. By accepting these Terms and creating a Numbrs Bitcoin Account, you receive a limited, non-exclusive, revocable license to use the Numbrs App in its current version for non-commercial purposes. A separate declaration of acceptance by Numbrs is not required. You must personally create a Numbers User Account, as we do not accept registrations carried out by third parties on your behalf. We reserve the right to refuse to accept your registration where we have reasonable cause, or should we believe that by doing so would result in us being in breach of any applicable law or regulation.
    2. Accessing the Services within the Numbrs App or the Numbrs Website

      Only after you have created a Numbrs User Account (see section 2.1) and start holding crypto assets in your account, will you have access to the full contents and services of the Numbrs App (see sections 3 and 4).

      The fees for the Services are displayed in the Numbrs App and/or the Numbrs Website. The fees for the Services shall be calculated in accordance with our fee schedule (“Fee Schedule”). Numbrs may propose modifications to the Fee Schedule at any time, upon at least thirty (30) days’ advance notice of such modifications to the User. The fees start to be accrued once you opened a Numbrs User Account and transferred first crypto assets to your Bitcoin Account. The fees will be charged to you on the last day of each quarter, for the three months of that past quarter. You agree that Numbrs will automatically send you a payment request for due fees towards the end of each quarter, which must be settled within seven (7) days of receipt. Numbrs retains the right to block your Numbrs User Account, including your Bitcoin Account and Numbrs Research, if your fees are overdue.
  3. Numbrs Research

    The Numbrs App and Numbrs Website offer you access to crypto research resources ("Numbrs Research"). Hereunder, you will find a compilation of articles with insights and forecasts from the field of Crypto. A part of the crypto articles are public and already accessible for free via the Numbrs Website and the Numbrs App. However, Numbrs will lock most articles, and make them only accessible after you opened a Numbrs User Account and started holding crypto assets in your Bitcoin Account for the first time.

    Articles are compiled and written by Numbrs experts in the crypto field. However, we would like to point out that this feature is for your information only and does not constitute any type of advice given by us to you. The compilation of these articles (even if locked) is in no way intended to serve you as investment advice and does not claim to be complete. The articles compiled by Numbrs experts are only intended to provide interested Users with an overview of recent developments in the crypto field as well as exciting new readings and to stimulate dialogue on this subject. We strongly advise you to always conduct your own investment research.

    You will also find webinars as part of the Numbrs Research, which can only be unlocked by the User by selecting one of the webinars and inviting a friend to Numbrs (the "Referral Program"). The invitation is considered successful once the invited friend creates a Numbrs User Account with Numbrs (see section 2.1) and transfers first crypto assets into his account (see section 2.2).

  4. The Bitcoin Account
    1. Description of the Service

      You may use the Bitcoin Account to send or receive crypto assets such as virtual currencies like Bitcoin ("Virtual Currency") to or from other persons and wallets.

      The Bitcoin Account is an online Virtual Currency storage service which allows you to hold, send and receive the Virtual Currency. The Bitcoin Account is a non-custodial wallet. This means that only you have access to your private key. Numbrs does not have access to your private key. Your private key is therefore not stored with the risk of total loss in case of bankruptcy, but is stored directly on your personal device. As a back-up, Numbrs keeps an encrypted copy on high-security servers in Switzerland which allows you to restore your Bitcoin Account on your device or on a new device.

      The Bitcoin Account is not a payment instrument, e-money wallet or a similar instrument and it does not offer a trading facility for Virtual Currency or other digital assets. The Bitcoin Account can only be used to hold, send and receive the Virtual Currency. You will appreciate that your Bitcoin Account is connected directly to the underlying Blockchain so that no transaction will pass through Numbrs.

      You are the owner of the Virtual Currency stored in your Bitcoin Account. You can access all information related to your Bitcoin Account through your Numbrs User Account opened within the Numbrs App or Numbrs Website.

      Your Bitcoin Account's initial balance will be zero. You can add the Virtual Currency to the Bitcoin Account by following the steps described in the Numbrs App or Numbrs Website.

      The use of auto trade robots (bots) or any other kind of automatic trading (buy, sell) software or devices on the Numbrs App is strictly forbidden. Numbrs reserves the right to suspend your accounts without notification, if suspected of such activities.
    2. Encryption & Backup

      To ensure secure use of the Bitcoin Account, you are required to choose a secure password in order to encrypt the Bitcoin Account. This password is required in addition to the Numbrs login and the security code every time you want to access the Bitcoin Account. In case you are already logged in, you are only required to provide the security code or your phone biometrics to access the Numbrs App.

      Additionally, you are requested to create a backup recovery key for additional safety against data loss (the "Backup Recovery Key"). The Backup Recovery Key allows you to restore the Bitcoin Account should your device be stolen or you want to restore the Bitcoin Account on a new or other device. The Backup Recovery Key is a mnemonic phrase in a certain order. You are solely responsible for remembering this mnemonic phrase and keeping it secure outside the Numbrs App or Numbrs Website. You are aware and acknowledge that the loss of your data, in particular of your private key, may lead to a complete loss of the Virtual Currency stored in your Bitcoin Account.
    3. Fingerprint and face recognition

      You can log into the Numbrs App using fingerprint or face recognition, provided that the device you are using supports this feature (e.g. TouchID or FaceID from Apple). Numbrs will not collect your biometric data. For more information on how fingerprint or face recognition identification works, please contact the provider of that feature.
    4. Transaction fees

      Transaction fees are charged in the Virtual Currency to your Bitcoin Account immediately and automatically once your transaction or other use of our service is completed. Numbrs does not charge any transaction fees as the transaction occurs directly from your Bitcoin Account to the underlying Blockchain. Numbrs does not compensate you for any such fees, therefore the amount of funds you add/withdraw to/from your Bitcoin Account may actually be smaller than the nominal amount you intend to transact.

  5. Security of your data

    Numbrs will continuously update (including security updates) the Numbrs App and Numbrs Website to the extent necessary to keep the digital Numbrs App and the Services in conformity and inform you accordingly, expand or modify the Numbrs App to respond to changing User interests, to fix technical errors and to introduce new features. We therefore recommend that you keep the Numbrs App and Numbrs Website, all other software on your device and your operating system up to date (for example, with respect to the latest security patches).

    The data transferred between the Numbrs App on your device or Numbrs Website and the Numbrs' systems is done via TLS/SSL connection. Your Numbrs User Account is stored securely by Numbrs in a data center in Germany certified according to the PCI-DSS and ISO27001 standards. Numbrs is entitled to adapt the technical measures for the protection of your data from time to time (e.g. due to further development of the state of the art or due to current knowledge in the field of cryptography).

    We may communicate with you via various methods including email. Although all of our emails are scanned for viruses, it is recommended that any attachment(s) be scanned by yourself as we cannot be held liable for any loss or damage caused by software viruses. If you choose to communicate with us via email, please be aware that email communications without the use of encryption, may not be the safest method of communication and third parties may be able to access it. Numbrs is not liable for such access. If you wish to guarantee the safety and confidentiality of any information you send to us via email, encryption methods should be used.

    Numbrs provides you with the Numbrs App and Numbrs Website in its current version. You are not entitled to request the maintenance of the Numbrs App and Numbrs Website in the state it was in when you accepted these Terms or at a later date. The Numbrs App supports mobile devices with iOS or Android operating systems. Numbrs reserves the right to offer the Numbrs App and Numbrs Website only for certain operating systems and/or only for certain versions of operating systems. We advise you to always keep your operating system up to date.

    We do not share your data with unauthorised third parties. Your information may be shared with authorised third parties in some situations, particularly when it is strictly necessary to provide and improve our services. Under no circumstances will we sell your data to third parties. You can find further information in our Privacy Notice which can be found by clicking on this link.

    The Numbrs App may not work on all devices. In particular, if you install the Numbrs App on a device with an operating system that has been modified in a way that breaches the requirements of the manufacturer or supplier of the device, including circumventing any restrictions without authorisation (a "Modified Device"), then it may not work and you should not use it on this device. We will not be responsible for any loss caused by use of the Numbrs App on a Modified Device or by the failure of the Numbrs App to work properly or at all in that case. When using a Modified Device, you will bear the burden of proof that a defect was not caused by the modification of the device.

    We will need to carry out planned and, occasionally, unscheduled technical maintenance from time to time, during which you will not be able to use the Numbrs App or Numbrs Website.

    We cannot guarantee that use of the Numbrs App or Numbrs Website will be uninterrupted or error-free. As with most services that are being provided online, we also cannot guarantee that the Numbrs App or Numbrs Website is free of any viruses or other malicious code, although we do everything we can to prevent this happening. If any defects occur, we request that you document these and send them to Numbrs in writing. Among other things, your information will allow us to improve our service. Please tell us about this using This does not affect your legal rights in relation to faulty or mis-described products.

    We may adapt the technical and organizational measures we use to protect your information (to reflect improvements in technology, for example) as long as this does not reduce the level of protection we apply to your information.

  6. Obligations of Numbrs

    We are under a legal duty to supply services that are in conformity with these Terms. Nothing in these Terms will affect the legal rights that you have under applicable laws and which cannot be waived by contract.

    Numbrs is committed to providing support for enquiries via email or via the live chat feature provided within the Numbrs App. Numbrs will normally respond to your enquiries within 2 working days. Please note that depending on the nature and extent of your question, an answer or solution may not be provided within 2 working days.

  7. Obligations of the User

    You agree that you will:
    • not try to access the account of a third party via the Numbrs App;
    • not transfer or try to transfer viruses, trojans, worms or other malicious code into our systems;
    • not hack, reverse engineer or manipulate our systems or try to do so;
    • not use the Numbrs App in a way that breaches any laws or regulations, or that might put us in breach of any laws or regulations;
    • not violate any contractual agreements with the providers of your account when using the Numbrs App; and
    • keep your data in the Numbrs App up to date.

    If we have reason to think that you are in breach of any of these Terms, we can temporarily suspend your access to the Numbrs App while we investigate the matter further. Numbrs will inform you about the suspension of your account, unless by doing so we would be violating any of our legal obligations. Should we decide that you have not breached these Terms, we will restore your access to the Numbrs App as quickly as we can.
    You are responsible for keeping your individual login details secret and secure and for protecting them from being obtained or used by any other party. You should not write them down or store them in a way that allows any other party to gain access to the Numbrs App or Numbrs Website. Should any of your devices on which you have installed the Numbrs App or where you may have consequently backed up your data, be lost or stolen, anyone in possession of the device may be able to access your Numbrs User Account. You are responsible for contacting us immediately in the event of the loss or theft, or in the event of your knowledge of any misuse of, or unauthorised access to your Numbrs User Account. You may contact our support team via Security instructions for handling your password and the security code can be found on our website.


    We are responsible to you for the loss or damage you suffer that is a foreseeable result of us breaching these Terms, except for where it is excluded by this section or otherwise in these Terms. Loss or damage is foreseeable if it is either obvious that it will happen or known by both you and us at the time you entered into these Terms that it might happen.


    We are not legally allowed to exclude or limit our liability where it would be unlawful to do so. This includes liability for death or personal injury caused by our negligence or the negligence of our employees, agents or subcontractors, for fraud or fraudulent misrepresentation, or where the Numbrs App or Numbrs Website is not fit for purpose, of satisfactory quality or not as described. The aforesaid limitations of liability shall not apply to any mandatory statutory liability, in particular to liability under the German Product Liability Act (Produkthaftungsgesetz), and liability for culpably caused injuries of life, body or health. In addition, such limitations of liability shall not apply if and to the extent Numbrs has assumed a specific guarantee.

    You are aware and acknowledge that the loss of your data, in particular of your private key, may lead to a complete loss of the Virtual Currency stored in your Bitcoin Account. Numbrs is not liable for any damage related to such data losses that are not attributable to our fault.

  9. Data Protection

    You may find more information regarding data protection in our Privacy Notice which may be found in this link.

    The services performed by us under these Terms are relying on the use of distributed ledger technologies, generally known under the name of "Blockchain" ("DLT-based Services").

    Transaction data related to your use of DLT-based Services may be recorded on a public ledger. Such public ledgers are designed and intended to immutably record transactions across wide networks of computer systems. Many such ledgers are open to forensic analysis (e.g. by law enforcement authorities or third parties) which can lead to de-anonymisation and the unintentional revelation of private financial information, especially when data stored on the public ledger is combined with data from other sources.

    Because public ledgers are decentralised or third-party networks that are not controlled or operated by us, we are not able to erase, modify, or alter your personal data from such networks, which will limit your rights to delete or modify your personal data as described in the Privacy Notice.

  10. How we can change the Numbrs App or these Terms

    We can change these Terms or change the Numbrs App for any of the following reasons:
    • to add new features to the Numbrs App, in particular in order to add storage functionality for additional types of digital assets other than Virtual Currency;
    • to withdraw any features or functionality;
    • to reflect changes (including expected changes) to or restrictions imposed by laws or regulations applicable to our Services, including any decision of a court, regulator or ombudsman;
    • to reflect any changes to our costs of providing the Numbrs App; or
    • to respond to any changes of the technology we use or might want to use.

    As these Terms have no expiry date and we hope that you will use the Numbrs App for a long time into the future, we may need to amend these Terms or the Numbrs App where we have a good reason that is not listed above.
    We will tell you about these mendments by:
    • bringing any amendments to your attention when you next access the Numbrs App or Numbrs Website and asking you to confirm your agreement to the changes; or
    • emailing you information about the amendment. We will use the email address you have provided. If we use an email to tell you about the amendment, we will aim to give you at least 30 days advance notice prior to the amendment coming into effect.

      If you do not want to accept the amendment, you can object in text form (e.g., by sending an email to within 30 days of receipt of the email. Otherwise the amendments shall be deemed approved. Numbrs shall specifically point this consequence out when announcing the amendments. On receipt of such an objection, Numbrs is entitled to terminate any agreement related to it before the changes take effect in line with Section 11.1, with the result that your Numbrs User Account will be deleted. For the objection to be deemed made in time, the dispatch date shall be decisive. In case of objection, the original terms and conditions shall continue to apply until termination.

      If you do not object to the amendments beforehand, the amendment will come into effect after the notice period (where notified by email) or immediately (where notified through the Numbrs App or Numbrs Website).
